深圳机场场道工程换填地基的沉降分析与观测

Settlement Analysis and Observation for a Refilling of Foundation in Shengzhen Airport

本文系统地阐述了深圳机场场道地基的沉降分析,沉降观测及沉降控制。分析和观测成果表明:场道的软土地基经过在拦淤堤封闭下换填后的总沉降量不大,且沉降速率较快。根据分析的结果提出了控制沉降工程措施。经过对观测资料的分析,利用调整混凝土道面浇筑的时间,严格控制地基的剩余沉降及差异沉降在设计允许的范围内。道面工程完成后的观测结果表明:其沉降控制是非常成功的。

The results of settlement analysis, settlement observation and control are included in this paper. The settlement of replaced foundation is relatively small, while the settlement rate is very large. A settlement control is presented in this paper. As a result of observation data analysis, we were succeeded in controlling the residual settlement by adjusting the construction time of concrete pavement. The results from observation after the pavement construction show that the settlement control is very successful.
